I enjoyed the animations of the animals playing more than I should have.

there should be a game like this maintaining an ecosystem

@mitos95176

The whole video is awesome, but the creative illustrations and the metaphors deserve special praise!
Moreover humans have become the most influential and the most powerful creators of music. Only time will tell if that brings more positivity or negativity to the universe.

@WINWINGAMING2010

That was a wonderful presentation that introduced a concept I had never before considered. Thank you.

@ICEcappcino

I love how they transform different environment into different music

@FFSboise

Just a quick note - "positive" and "negative" are confusing to students (and practitioners) just because of the reason alluded to in the video - positive often implies beneficial, and negative the opposite, but it really describes the direction the response has to the disturbance.  I've been using "reinforcing" and "balancing" (respectively) - seems to work better.

I found out addictions are just that, a positive feedback loop. 
Pleasure feeds back the system, so you do more of the same action that got you pleasure, until you realize you're screwing yourself.

One of my most favourite explainer videos.

@srikar2100

This is a fantastic video - mainly the illustrations of symphonies in different ecoystems.

I wish we would teach about feed back loops in K-12 education. It is a very important mathematical concept that really lies at the heart of just about everything, from Economics to Biology. 

@oonmm

All i wanted was to see those animals play their instruments, and you gave it to me! <32333 I can't express how happy i am for this, i loved those lill creatures playing their music. Thumps upp all the way!!

@DavidFrat123

I would've enjoyed hearing a bit about feedback loops in physiology and development too. 

@CMBrannstrom

I like to feel intelligent while watching cartoons.

@bclaus0

Interesting, but when the animals started jammin' I really didn't listen to the explanation anymore. :P

@chloesolum3552

these metaphors are absolutely insane, fire vid, thoroughly enjoyed

@katiefoster4544

Great video! Though I'm wondering if anyone else noticed they pronounce "humus" (Hue-mus) like "hummus" (Hum-mus), which is a Greek dip made of chickpeas. I love the harmony metaphor to illustrate the concept of complexity.
